will zig-zagging help us to escape black hole?

Question

When fisherman wants to go to the ocean from their jetty in the riverside during high tide, they move zig-zag across the river to avoid taking full force of the tide. Therefore, even their small engines can take them to the ocean. Will this method work to help us escape the gravity of black hole ?

Answer 1

First to clear up a couple misperceptions of previous answers. Black holes do not "suck in" or pull in matter. If the sun collapsed into a black hole tomorrow, Earth and all the other planets (yes, even Mercury) would continue to orbit it in exactly the same fashion that they do now. Outside of their event horizons, black holes only differ from other gravitational sources in magnitude. The gravity from a black hole behaves just like the gravity from any planet or star.

Also, while it's true that your ship will be torn apart by the time it crosses the event horizon of a regular black hole (a few times as massive as our sun), there are very large black holes at the center of galaxies (including our own) that have masses of millions of stars. These black holes have the unusual property that their event horizons are large enough that a spaceship could pass thru it comfortably, only experiencing a small amount of stretching. Of course it would be torn apart soon afterwards as the gravitational forces rose exponentially, but it could certainly cross the event horizon intact.

Now to actually answer your question, zig-zagging is probably a waste of rocket fuel. If you find yourself falling towards any gravitational source, be it a planet, star, or black hole, your choices are always the same. You can accelerate towards the object but slightly off-skew, hoping to use its gravity as a boost. Or, you could point your rocket away from it and fire at full thrust. Or the third choice would be, point your rocket perpendicular to it and fire full thrust.

The correct answer is to do the third choice. If you do the first, you'll be passing so close to it that you'll either crash into it (planet or star) or get ripped apart by the tidal forces (black hole). If you do the second, you MIGHT escape if you have a gargantuan amount of rocket fuel and haven't built up much speed already falling towards the source. But rocket fuel is finite, and gravity just keeps on pulling forever.

Due to the quirky way that orbital dynamics work, your best bet is to fire your rocket perpendicular to the direction you're falling. This will put you into an orbit around the gravity source. From there, further firing of your rocket in the direction of your orbit will give you the angular momentum to widen your orbit more and more, until you're able to break free altogether.

Whenever people launch a rocket or space shuttle from Earth, they always want to launch it as close as possible to the equator, and also launch it eastward rather than straight up. This is the same principle, namely that you will use a LOT less energy if you let the planet "fling" you up rather than just trying to go directly straight up.

Answer 2

That radiation you point out comes from textile being sped up into the black hollow itself or right into a torus around it. the textile is speeded as much as very virtually easy velocity by applying the black hollow's huge gravity and friction interior that best-velocity textile generates radiation. maximum of it is going to ultimately be drawn each and each of ways into the black hollow, yet nonetheless a brilliant volume escapes outward and that's what we are able to come across. Hawking Radiation isn't purely no greater suitable than an unproven concept yet in addition a completely distinctive technique than defined above.

Answer 3

No.

Black Hole actualy wrap space, you can't escape it couse there is no way out once you are inside.

Once inside the Black Hole, everything that is in it will end up in the middle on the Black Hole, more then this, everything will alwase get closer to the center.

Answer 4

I think it may help until you are past the event horizon. At that point not even light will escape, so it would kind of be like the fisherman getting caught in a huge whirlpool too powerful for his engines.

Answer 5

actually, the gravitational pull at the event horizon (where normal space ends and black hole begins) will be so strong that you and your space ship won't survive it... so no need to zig zag... that only works for antelops...

Answer 6

No. Black hole pulls you in rather than hits you. No matter which direction you are travelling, you will die.

Answer 7

you are a Genius!
